Go to hardware store and purchase a spray bottle. Fill it with water and when it is dark, start your truck, pop the hood and spray the wires with water from your new spray bottle. Stand back and enjoy the light show. Most of the current going to the plugs is being used to produce the fantastic light show. That is why it is misfiring.

well..drove the truck this morning and it got a little worse and the check engine light came on. So i took it up to advance and they ran the test and it said number 4 was misfiring, and it would most likely be my plug wires. So..i'm gonna go ahead and try and change those in the next few days and keep you guys updated. hopefully this will fix it. thanks for all the help though guys, especially jbrew. i'll probably get the plug wires online and pick them up in store. Does anyone know the difference between the regular motorcraft set of spark plug wires and the duckbill set?
thanks again

btw, the number 4 plug is the one closest to the cab on the passenger side correct?
